Bubbles in drywall
I recently noticed this wave-like bubbling in the drywall in our powder room. This is a townhouse and none of our plumbing goes through this wall, to my knowledge. This wall is shared with a neighbor's unit. If there is water in the wall, I need to notify the HOA right away. However it doesn't feel damp and I can't find any other signs of water.
I am sure it was not like this when I painted a few months ago. When I feel it, it just feels dry and like air bubbles under the paper layer.
Is there anything else that could explain this besides water? If it's likely water I will need to get the HOA to have someone come in and open up the wall :(
